A sample answer to question 1

Which KPIs would you use to manage a production area, and why?

I'd use a balanced set linked to the business goals. Safety first: accident rate, near-miss reports and audit completion. For quality: first-pass yield, scrap and rework percentage, customer complaints and defects per million. For delivery: schedule adherence, on-time in full and WIP levels. For efficiency: OEE, broken down into availability, performance and quality, plus labour productivity and downtime causes. For cost: cost per unit, material usage variance, overtime and energy per unit. I'd also include people measures like absence and training matrix completion. I'd show them on visual boards by line and review them in a daily tier meeting, with a deeper weekly look at trends and actions. A KPI is only useful if it triggers action, so every red measure needs an owner, a countermeasure and a date. I'd also avoid too many measures, so the team stays focused.

Common mistake to avoid: Listing too many KPIs; Measuring without acting
